Nitrogen Rich Carbon Nitride Synthesized by Copolymerization with Enhanced Visible Light Photocatalytic Hydrogen Evolution

Abstract

A novel method for preparing visible light enhanced photocatalytic carbon nitride was proposed by copolymerization melamine with nitrogen rich precursor. The synthesized carbon nitride named CN-THDTX with special structure exhibiting strong visible light absorption ability. XPS results confirmed the as-repared CN-THDTX contain abundant nitrogen in a range of 53.0~77.4 at. % . And the band gap can be efficiently controlled by changing the ratio of THDT. Under visible light irradiation, CN-THDT0.15 exhibited the highest hydrogen production 2.3 times than pure g-C3N4. After twelfth circling experiments and 48 hours continue hydrogen production test, the photocatalytic activity of CN-THDT0.15 shows negligible subsiding, suggesting the prepared sample has great potential application for photocatalytic generating hydrogen from water splitting.
